Figures are entered as published in the source datasheet; m³/h values are m³/min × 60. Final selection must be verified against duct resistance, medium and site conditions.
How to read these figures
- · The flow range in the summary takes the minimum and maximum across all operating points
- · The full table keeps every flow figure from the source datasheet
- · Speed, noise, weight and connection dimensions follow the official product manual
Series capability
- · Wide operating range
- · Compact direct drive
- · Demand-based control
- · IP rating, electrical parameters and connection dimensions: to be added once model documentation is confirmed
Shared Technology Platform
Four series, one 3rd-generation efficiency platform
PM direct drive + Smart VFD + Aerodynamic optimisation + Data O&M — Full technical explanation on the Technology page →
Permanent-magnet motor
No sharp drop-off at part load; less energy under varying conditions
Direct drive
Less transmission loss and fewer wear parts, so less maintenance and downtime
Smart VFD · demand-based airflow
A small drop in speed can mean a much larger drop in power
3D-flow impeller + tapered volute
More useful output under the same conditions
